Ha! Hahahahaha! It worked! She set the Jedi on the Sith, and Palpatine killed him! Sidious won.

Might explain the sealed message delivered to Sidious later that day via one of her proxies she hadn't thought was compromised, which when opened simply reads:

Your move, now. 

And is signed with a sketch of a water-lily. 

So, the game continues.

Sidious has several dozen bouquets of flowers, enough to fill a small room, delivered to Palpatine's quarters at the Jedi Temple. Lilies as the centerpieces, with other flowers expressing gratitude, triumph, strength, intelligence.

Several of Sidious's other proxies, agents, and the like receive a single lily, or a card with a picture of a lily. Their names, organized in the order Sidious finds out about the gifts (which is different than the order sent or received in), spell:

LET'S GET LUNCH

(And some of the Sith-friendly bills passed previously get highlighted as something to possibly overturn or amend by a few different committees.)

How elaborate. She's got quite the flair for the dramatic.

Sidious can't allow such a deep knowledge of her network to go unchallenged, so... She orders Master Palpatine takeout. The really bad kind, where everything on the menu is deep-fried, at least fifty percent grease by volume, and nothing costs more than four credits.

Senator Vendar helps get a couple of those bills amended, and, just before the next recess, calls Lily to invite her to see the villa Sangua had designed for her on Alderaan. Construction was just completed.

She seems to be currently eating bad takeout she's stacked up in the minifridge in her suite. What a thoughtful gift.

"I'd love to see it. Are Nexuha and Sangua joining us?"

"That is the plan."

"And- I will try to arrange for more, ah, palatable meals."

She shoves a cold breaded mystery """vegetable""" in her mouth, at least managing to swallow before saying, "No idea what you're talking about."

"...I see."

"Though if Nexuha is cooking..."

"No, no, I'm not sure you deserve it any more."

"Senators shouldn't be judgmental of other beings' sustenance habits," she says, and eats another mystery object. 

"That might be relevant if I employed Nexuha's cooking skills in a Senatorial capacity. Which I don't. This is me speaking as a private citizen, my right to do enshrined in the constitution of the Republic."

"So you don't want to rescue me from my unrefined palate?"

"Honestly Lily, I'm concerned you're already past saving. Do you get special Jedi training on how to survive eating those sorts of things, or...?"

"Being able to politely eat anything put in front of me is a very essential skill on certain missions."

"So yes. My goodness."

"A bigger challenge than you can handle?"

"The problem is clearly systemic, endemic to the Jedi Order."

"Sounds like you're giving up, then."

"Merely regrouping. I need to consider my angle of attack carefully. One does not undermine such an organization overnight."

"You could start with treating me to a nice dinner..."

"I'll be sure to lay in the appropriate ingredients."

"I'll look forward to it."
